Step 6: Check the router channel WiFi routers usually use specific channels for communication. If you have multiple WiFi networks at home, your router may use the same channel as your neighbor's router.This will lead to channel congestion and interference, thus affecting the stability of the network. Therefore, you need to check the channel used by your network and make sure that it does not conflict with other networks. Step 7: Check the router settings.
